Primary oocyte is surrounded by a single layer of follicle cells
7 million formed before birth. Only 450 will reach ovulation.
Home5Primary follicle
FSH activates primordial follicle.
Follicle cells divide to form many layers.
Home6Ovarian developmentSecondary follicle
Ovary adds layer of cells (theca) outside the follicle cells.
Both layers secrete female hormones into fluid-filled spaces.
Home7Graafian (mature) follicle
Grows to about 10mm diameter due to stimulation by oestrogen.
Seconday oocyte and 1st polar body formed after surge of LH
Home8Ovulation
Surge in LH causes Graafian follicle to release secondary oocyte.
Secondary oocyte carried into fallopian tube.
Home9Corpus luteum (yellow body)
Formed from remains of the Graafian follicle. Its growth is stimulated by LH. It secretes Progesterone (and some Oestrogen).

If fertilisation does not occur the corpus luteum degenerates.
Probably due to chemicals it releases itself.
